Preheat oven to 400 degrees. Mix all seasoning ingredients in a small bowl and set aside. If you decided to go with fresh ingredients (I'm lazy, so obviously I decided to use frozen), slice the onion and bell peppers into strips. Place in a large 9x13 in casserole dish. If you went the frozen route, I just emptied the bag into the dish to cook with the chicken.

Slice chicken into thin slices and add to the same dish. Sprinkle seasoning over meat and veggies. Drizzle avocado oil over everything and toss. Bake in preheated oven for 35 to 40 minutes. When finished, squeeze half a lime over the dish and top with cilantro.
